Precaution to be taken when replacing and servicing the Laser Pickup.The AEL (Accessible Emission Level) of Laser Power Output for this model is specified to be lower than Class I Requirements.However, the following precautions must be observed during servicing to protect your eyes against exposure to the laser beam.(1) When the cabinet has been removed, the power is turned on without a compact disc, and the Pickup is on a position

outer than the lead-in position, the Laser will light for several seconds to detect a disc. Do not look into the Pickup Lens.(2) The Laser Power Output of the Pickup inside the unit and replacement service parts have already been adjusted prior

to shipping.(3) No adjustment to the Laser Power should be attempted when replacing or servicing the Pickup.(4) Under no circumstances look directly into the Pickup Lens at any time.(5) CAUTION - Use of controls or adjustments, or performance of procedures other than those specified herein may result

in hazardous radiation exposure.

Precaution to be taken when replacing and servicing the laser pickup.The following precautions must be observed during servicing to protect your eyes against exposure to the laser.Warning of possible eye damage when repairing:If the AC adaptor or batteries are connected when the top houising (disc cover) of the unit is removed, and the PLAY key ispressed, the laser will light up during focus access (2-3 seconds). (Fig. 2-1) During the operation, the laser will leak from theopening between the magnetic head and the mechanical chassis (Fig. 2-2). In order to protect your eyes, you must not lookat the laser during repair. Before repairing be sure to disconnect the AC adaptor and remove the batteries.

DISASSEMBLY

Cares before disassemblingWhen assembling the machine after disassembling orrepair, observe the following requirements so as to ensuresafety and performance.1. Remove the batteries from the machine, and take out the

mini-disc.2. When assembling after repair, be sure to restore the

initial location of wires.Since the screws are small, incorrect fixing may result inmalfunction.

3. When repairing, pay utmost attention to static electricityof IC.

REMOVAL PROCEDURESTEP FIGURE

Caution:Carefully handle the main PWB and flexible PWB. After removing theflexible PWB (1*) for the optical pickup from the connector, do nottouch directly the front end of flexible PWB with your hand so as toprevent damage of optical pickup by static electricity.

NOTES ON SCHEMATIC DIAGRAM

• Resistor:To differentiate the units of resistors, such symbol as K andM are used: the symbol K means 1000 ohm and the symbolM means 1000 kohm and the resistor without any symbol isohm-type resistor. Besides, the one with “Fusible” is a fusetype.

• Capacitor:To indicate the unit of capacitor, a symbol P is used: thissymbol P means micro-micro-farad and the unit of thecapacitor without such a symbol is microfarad. As to electro-lytic capacitor, the expression “capacitance/withstand volt-age” is used.(CH), (TH), (RH), (UJ): Temperature compensation(ML): Mylar type

• The indicated voltage in each section is the one measuredby Digital Multimeter between such a section and the chas-sis with no signal given.

• Parts marked with “ ” ( ) are important formaintaining the safety of the set. Be sure to replace theseparts with specified ones for maintaining the safety andperformance of the set.
